Bullet-loading structure of toy gun

ABSTRACT

In a toy gun with a bullet-loading structure, a cylinder, a piston, a final gear, and a pull rod are mounted in a gun body. The piston and the pull rod are driven by the rotation of the final gear. An actuation time of the pull rod is later than that of the piston to enable the piston to suck a lot amount of gas before the loading of the bullet, thereby preventing a gun tunnel from being blocked by the raised bullet and providing the simulated recoil effect of real shooting so as to promote the shooting performance of the toy gun.

FIELD OF THE INVENTION

The present invention relates to a bullet-loading structure of a toy gun, and more particularly to a bullet-loading structure, wherein an actuation time of the pull rod is later than that of the piston so as to prevent a gun tunnel from being blocked by the raised bullet, thereby providing the simulated recoil effect, which simulates the real shooting, so as to promote the shooting performance of the toy gun.

BACKGROUND OF THE INVENTION

Referring to FIG. 9 through FIG. 11, wherein FIG. 9 and FIG. 10 are cross-sectional views showing the bullet-loading states of the conventional toy gun. This conventional toy gun utilizes a high torque motor to drive a final gear 20 for further driving a compressible spring 50 and a piston 40 having a rack 30. The compressible spring 50 is compressed when the piston 40 is shifted backward. At the same time, a certain amount of gas is sucked into a cylinder 60 for being compressed. When a tooth-shaped arc edge 201 is disengaged from the rack 30 located on the lower portion of the piston 40, the bullet 10 is strongly pushed out via a bullet-pushing outlet 80 by the piston 40, which utilizes the push force provided by the released compressible spring 50.

However, a slide block 203 located on the rear end of a pull rod 70 has already been touched by a protrudent pillar 202 mounted vertically on one side of the final gear 20 before the suction of the gas into the cylinder 60. With the rotation of the final gear 20, the bullet-pushing outlet 80 of the pull rod 70 is shifted backward for loading the bullet. At the moment, the bullet-pushing outlet 80 is jammed by the bullet 10. As a result, the gas suction is affected. As shown in FIG. 11, a cross-shaped trench 801 is too small to increase the gas-suction amount even if it has been formed on the front end of the bullet-pushing outlet 80 for gas suction. Besides, the sucked gas is more insufficient since the piston 40 is pushed back rapidly. In addition, the centralization of the exhausted gas is also affected by the formation of the cross-shaped trench 801, resulting in the reduced shooting performance and the lack of recoil effect in real shooting.

SUMMARY OF THE INVENTION

Whereas the foregoing description, the present inventor makes diligent studies in providing an improved structure so as to overcome the conventional problems.

It is a main object of the present invention to provide a bullet-loading structure, wherein an actuation time of the pull rod is later than that of the piston to enable the piston to suck a lot amount of gas by using the maximum aperture of the bullet-pushing outlet, thereby preventing a gun tunnel from being blocked by the raised bullet and providing the simulated recoil effect, which simulates the real shooting, so as to improve the shooting performance of the toy gun.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The above-mentioned features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the drawings.

Referring to FIG. 1 and FIG. 2, a piston 3 is slidable in a cylinder 2 in a gun body 1 of the present invention and a compressible spring 4 is located between the piston 3 and a rear end of the gun body 1. The backward shifting of the piston 3 in the cylinder 2 causes the suction of the gas. Besides, the gas is compressed immediately when the piston 3 is shifted forward by the resilience force provided by the recovered compressible spring 4, which is compressed previously, such that the compressed gas is exhausted from a gas outlet 21 of the cylinder 2 for shooting a bullet.

The power for shifting the piston 3 backward is supplied in accordance with the following description. A rack 31, which is mounted on the lower edge of the piston 3, is engaged with a final gear 5. The final gear 5 is a semi-gear and comprises a releasing arc edge 51 and a tooth-shaped arc edge 52, wherein an internal gear 53, which is mounted on one side of the final gear 5, can be driven by a motor (not shown) via a gear set. In addition, a protrudent pillar 54 is mounted vertically on the other side of the final gear 5 between a start end 55 and a stop end 56 of the tooth-shaped arc edge 52. Detailedly speaking, the protrudent pillar 54 is located near the center portion of the tooth-shaped arc edge 52 deviant toward the stop end 56. In other words, with respect to an axis of the final gear 5, an included angle between the protrudent pillar 54 and the start end 55 is θ1 and an included angle between the protrudent pillar 54 and the stop end 56 is θ2, wherein θ1 is larger than θ2, as shown in FIG. 8.

Besides, a curved pull rod 6 located on the bottom of the cylinder 2 is provided for controlling the loading of the bullet, wherein a front end of the pull rod 6 is locked to a bullet-pushing outlet 7, which is sleeved to a gas outlet 21, wherein the pull rod 6 is held in a gun tunnel of a barrel 8 and further comprises a slide block 61 on the rear end thereof and on one side of the protrudent pillar 54 of the final gear 5. Besides, the pull rod 6 is securely coupled to the gun body 1 via a recoil spring 9. The slide block 61 has a bevel edge 611 having an irregular curve. When the final gear 5 is in operation, the protrudent pillar 54 slides along the bevel edge 611 of the slide block 61 to push the pull rod 6 backward until the protrudent pillar 54 reaches a rear end of the bevel edge 611. By using the curve design of the bevel edge 611, the force applied by the protrudent pillar 54 for pushing the pull rod 6 can be reduced. Lastly, the pull rod 6 returns to its previous position by using the resilience force of the recoil spring 9.

Referring further to FIG. 3 through FIG. 8, as shown in FIG. 3, in the initial state, a magazine (now shown) can push the bullet 10 upward to block it by the bottom of the bullet-pushing outlet 7. At the same time, the final gear 5 is engaged with the rack 31 located on the lower portion of the piston 3. As shown in FIG. 4, a torque motor is actuated to rotate the final gear 5 counter-clockwise. At the same time, the piston 3 is also driven to shift back for gas suction.

As shown in FIG. 5, when the final gear 5 is rotated to the middle region between the start end 55 and the final end 56 after it is operated for a certain period of time, as shown in FIG. 8, the bevel edge 611 of the slide block 61 is touched by the protrudent pillar 54 so as to make sure that the gas can be sucked into the piston 3 fully before the loading of the bullet 10. After the continuous operation of the final gear 5, the protrudent pillar 54 slides along the bevel edge 611 to push the pull rod 6 backward, whereby the bullet 10 is released from the blocking of the bullet-pushing outlet 7 and thus raised to be located in the barrel 8.

As shown in FIG. 6, when the protrudent pillar 54 slides to the rear end of the slide block 61, the force applied by the protrudent pillar 54 for pushing the pull rod 6 can be reduced by using the curve design of the bevel edge 611 such that the pull rod 6 is shifted forward by the recovered resilience force of the recoil spring 9 (referring to FIG. 1), whereby another bullet 10′ is blocked by the bullet-pushing outlet 7 to wait for next shooting procedure. After that, as shown in FIG. 7, when the final gear 5 is rotated to the releasing arc edge 51 for being disengaged from the rack 31 of the piston 3, the piston 3 is shifted forward by using the force of the compressible spring 4 to exhaust the gas in the cylinder 2 for pushing the bullet 10 in the barrel 8 to the outside.

As described above, in the present invention, the actuation time of the pull rod is later than that of the piston so as to form a time difference in the displacement of the bullet-pushing outlet and the piston. In other words, the process time spent by the tooth-shaped arc edge in engaging with the rack of the piston is larger than the process time spent by the protrudent pillar in sliding along the slide block. Besides, the bullet-loading process is completed during the process of sucking the gas, whereby the piston can suck a lot amount of gas by using the maximum aperture of the bullet-pushing outlet and can shift the bullet-pushing outlet by using the protrudent pillar for loading the bullet so as to prevent the gun tunnel of the barrel from being blocked by the raised bullet. As a result, the gas-suction capacity of the piston is increased, thereby promoting the shooting performance of the toy gun by providing the simulated recoil effect of real shooting.
